upgrade configoption product with API

[developer _WHM_CS]

Hello

We need to have Upgrade option on configoption of a service through API According to the link below
https://developers.whmcs.com/api-reference/upgradeproduct/

here is our sample code:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.mydomain.com/includes/api.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
http_build_query(
array(
'action' => 'UpgradeProduct',
// See https://developers.whmcs.com/api/authentication
'username' => 'IDENTIFIER_OR_ADMIN_USERNAME',
'password' => 'SECRET_OR_HASHED_PASSWORD',
'serviceid' => '1',
'paymentmethod' => 'paypal',
'type' => 'configoptions',
'configoptions' => array(50 => 80, 30 => 81 ,40 => 23);
'responsetype' => 'json',
)
)
);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);

configoptions is an array
The Numbers 30, 40, 50 are configoption ID
and the Numbers 23, 81, 80 are new value

Then return this :

result":"success","configname1":"Slaves","originalvalue1":"0","newvalue1":"80 x Slaves","price1":"313,227,380 USD","configname2":"Mini Slaves","originalvalue2":"0","newvalue2":"81 x Mini Slaves","price2":"234,920,535 USD","configname3":"Micro Slaves","originalvalue3":"0","newvalue3":"23 x Micro Slaves","price3":"104,329,507 USD","subtotal":"652,477,422 USD","discount":"0 USD","total":"652,477,422 USD","id":"6491","orderid":6425,"order_number":"4918850114","invoiceid":"84001"}

And Why hit new value to the options name ???
80 * Salves !!!
81 *  Mini Slave!!
23* Micro Slave!!
